WASHINGTON, D.C. – The Federal Bureau of Investigation (FBI) is warning Americans not to respond to scam text messages related to toll fees, after receiving more than 2,000 complaints this month, according to ABC News.

These messages impersonate official toll collection agencies and attempt to trick mobile phone users into revealing financial information, such as credit or debit card details or bank account numbers.

Known as “smishing” (SMS phishing), this form of fraud uses deceptive text messages to mislead recipients into sending money or sharing sensitive personal data.

The FBI says these messages are spreading from state to state and often use nearly identical language. They falsely claim that recipients have unpaid or overdue toll fees, warning that this could result in fines or suspended driving privileges.

The FBI urges anyone receiving such scam messages to file a complaint with its Internet Crime Complaint Center (IC3) at www.ic3.gov and to delete the messages immediately.

Last week, cybersecurity firm Palo Alto Networks reported that a threat actor had registered more than 10,000 domains to impersonate toll collection services and package delivery companies across at least 10 U.S. states and Ontario, Canada.

While Apple blocks links in iPhone messages from unknown senders, the scam tries to bypass this security by prompting users to reply with “Y” to reopen the message.
